基于milkv-duo环境编译 ​

Milk-V Duo是一个基于CV1800B芯片的超紧凑嵌入式开发平台。它可以运行Linux和RTOS，为专业人士、工业ODM厂商、AIoT爱好者、DIY爱好者和创作者提供了一个可靠、低成本和高性能的平台。

安装 ​

虚拟机 ​

VBox + Ubuntu20.04

依赖 ​

bash
sudo apt install pkg-config build-essential ninja-build automake autoconf libtool wget curl git gcc libssl-dev bc slib squashfs-tools android-sdk-libsparse-utils jq python3-distutils scons parallel tree python3-dev python3-pip device-tree-compiler ssh cpio fakeroot libncurses5 flex bison libncurses5-dev genext2fs rsync unzip dosfstools mtools tclsh ssh-client android-sdk-ext4-utils
wget https://github.com/Kitware/CMake/releases/download/v3.26.4/cmake-3.26.4-linux-x86_64.sh
chmod +x cmake-3.26.4-linux-x86_64.sh
sudo sh cmake-3.26.4-linux-x86_64.sh --skip-license --prefix=/usr/local/

添加一些package ​

bash
source ./build/cvisetup.sh
defconfig cv1800b_milkv_duo_sd 
menuconfig
# 可以添加或者删除一些软件和配置

编译打包 ​

可以查看env.sh源代码

说明每个平台是不一样，希望大家稍微修改哈

echo "OUTPUT_DIR: ${OUTPUT_DIR}"  # @build/milkvsetup.sh

if [ $# -eq 1 ];then
 clean_all
fi
build_all
pack_sd_image

执行如下命令：

bash
# 第一次编译时候可以用
./env.sh
# 不是第一次编译时候可以用，先清理缓存
# ./env.sh arg1     arg1表示参数1，内容没固定，随便写
./env.sh 1

或者想在镜像添加一些文件，如python，gdb等，需要如下命令：

bash
source ./build/cvisetup.sh
defconfig cv1800b_milkv_duo_sd
menuconfig
# 可以选择你喜欢的东西，然后可以运行
build_all
pack_sd_image

image ​

上述步骤，正常运行编译打包，导出image镜像，如下：
install/soc_cv1800b_milkv_duo_sd/milkv-duo.img

烧录方式可以是SD卡或者其他工具

判断是否成功 ​

  • 测试ping 192.168.42.1
  • 需要安装依赖驱动哈

建议 ​

  1. 不要安装在Windows系统下编译
  2. 即是在Windows用wsl环境下配置，不建议
  3. 在Linux或者容器或者虚拟机，不要直连Windows下路径，有时候莫名其妙出一些问题
  4. 搬抄按照步骤去做，发现有一些依赖文件没安装，需要分析一下
